During the period from 1977 to 1982 a trial was carried out in Jacarezinho, PR, Brazil, with 18 introductions of coffee (Coffea arabica L.) to assess the yield potential, plant architectural features, fruit maturity, bean characteristics and reaction to leaf rust and leaf miner. Results were compared with those of cultivar Catuaí-Amarelo which is extensively planted in Brazil and lcatu. Differences in yield and other traits among plants were significant. Nine introductions showed similar yield when compared with Catuaí-Amarelo (4,629 kg/ha). Four have shown dwarf habit, and fourteen presented early fruit maturing characteristic. All introductions were susceptible to coffee rust, produced high percentage of flat beans and low percentage to shell-beans. The introduction T-974 was lesser attacked by leaf miner.
